Device Display Meaning for the LMV5x System Corrective Action
20 Fault when calling the "ParAccess()" function
21 Written EEPROM block unequal RAM block
22 CRC of page is faulty
23 Matching fault µC1, µC2 when saving the error page
63 Any #
No display of
error (can only be
read out via
eBus)
Unit is error-free None
Any # Fault during restoring of lockout information
01 When reading from EEPROM (initialization)
02 When test writing in the initialization
03 No write access to error page in init.
04 Repetition counter "Internal fault" has elapsed
71 Any # Manual Lockout Lockout was made manually via contact
This lockout occurs when escape and enter on the AZL
are pressed simultaneously. This lockout also occurs
when the remote reset X4-01.4 is energized when an
alarm condition does not exist.
Any # Plausibility fault in connection with fault entry
01 Fault in "seterr()"
02 Fault in "seterr()"
03 Fault in "error_manager()"
04 Fault in "storeerr()"
Any # Basic unit has detected wrong state of the auxiliary 3 actuator
01 CRC error
02 Key error main loop counter
03 No feedback for max. number
Any # Basic unit has detected wrong state of the air actuator
01 CRC error
02 Key error main loop counter
03 No feedback for max. number
Any # Basic unit has detected wrong state of the gas actuator
01 CRC error
02 Key error main loop counter
03 No feedback for max. number

1) This fault occurs when an un-addressed actuator is
connected to the CANBus. Addressing the actuator
should eliminate the fault.
2) Check CANBus cabling. Ensure that all cable shields
(screens) which are located in the cable sheath are
terminated correctly at each actuator, O2 module, and
at the LMV5x...
3) Check each CANBus connector to ensure proper
termination (no conductors exposed on the back of the
plug)
4) If fault occurs sporadically: Reduce electrical noise.
5) If fault occurs constantly: Replace actuator according
to diagnostic code.

1) Reset the LMV5
2) If fault occurred after changing a parameter, check
the parameters that were last changed.
3) If fault cannot be rectified by the reset: Restore
parameters form the AZL to the LMV5
4) Replace the LMV5
